Abstract:
Amongst many control techniques developed
and used for induction motor drives, Flux or Field
oriented control is probably the most popular control
method used for high-performance induction motor
applications. The field oriented control algorithm
involves heavy mathematical computations and therefore
its implementation requires a high execution speed
processor/controller to meet all practical system
demands. However, the inherent computational power of
the Digital Signal Processors (DSP) permits very fast
computations. It provides user an easy way to implement
various control techniques of induction motor drives for
real time simulink model.
In this paper, a simulation model of a current controlled,
voltage source inverter fed, rotor flux based indirect field
oriented drive system for an induction motor is developed
in MATLAB environment with simulink and its
performance is tested by implementing it on a tailor
made experimental setup of 1 HP induction motor and
DSP controller board-DS1202. The test results of the
induction motor drive are studied for various operating
conditions.
